Application fledMarch 29,- 1923. Serial No. 628,542. i

' Bc it known that I,y Muti: SLAWIENSKI, a citizen 'of Polanchicsiding at 38 North 3rd Street, Camden,

ments for otor Cycles, of whichpthe following is aspecication,

`My invention lrelates to new and useful improvements in a handle attachment. for

motor cycles, and has. for its primary object*A to provide meansfor maintaining` the rotat.-

able grip, which controls the fuel supply or ignition mechanism,` and the like', in any'del sirable adjusted position.. l

Another ohJc'ct ot' this invention is to 1in-4 prove theconstructmn and arrai'igement of devices ot' like character in vorder that the handle'gripmay be rotated with little -eort on Itliepartvof thcl operator andin4 which the' wear'on the`- operating parts will be re duced to Ia minimum.

A further object' of my invention is to provide an attachment that maybe readily applied or' alixedto the handle'of motor cycles already in use and having different sized `handle barsand grip, suchobject being accomplished by means of two` split rings in whichthe elements of each are hinged together and fastened about their re spective parts byattaching mea-ns such as bolts and` nuts. One of the split rings is providedy with acorrugated portion with which coacts a Wheel'journalled on a spring actuated lever carried by the other ring.

A still further object of the 'invention' contemplates the provision lof means vto latch the spring actuated lever in an inoperatedl position at Which'time the Wheel of the lever will be held outl of contact with the corrugated ring.' f

With these 'ends in view, this invention consists inthe details of construction and combination of elements hereinafter` set forth'and then specifically designatedby the claims.

In Order that those Skiiied in the we m which this invention appertains, may understand how to make and-use t'he same, I will describe its construction in detail, referring bynuinerals to `thev accompanying drawing forming which -x Fig. 1, is a fragmentary perspective view of a motorcycle handlel illustrating the application of my invention.

in the county of Camden; and State of New Jersey, have invented new and useful,Improvements in Handle Attach a part of this "application, in*y Fig. 2, is an enlarged sectional side e1ev`a tionof Ithe vattachment removed from the handle, and

Fig. 3, is an end View of the corrugated ring.

In carrying vout 'my invention as herein embodied 2V represents a handle of any ori dinaryor desirable construction :is-'usually employed upon motor cycles and' comprises a handle bar 3 with -a' grip et rotatably mounted thereon. In actual practice this griphas connectionwith suitable mechanism ,for'controlling the lgnition, fuel supply and thelike.

' On the handle bar adjacent the grip is de# tacliably mounted a split ring 5 "consisting of a lpair of similar substantially semi-circui lar' members 6 and 7 hinged together as' at' 8 whereby said ring may be opened and closed for detachableconnection to the handle bai' where it is held in its adjusted position by suitable fastening means 9'such as a bolt and'nut'or their equivalents.A bolt and nut as a fasteningmcans is preferredzand where s'uch isy used the `former `passes through flanges l0 produced on the The ends of the ring members opposite the hinge.

The ring 5 is ciicuinferentially corrugated adjacent, one end or edgeonly as indica-ted by the numeral ll leaving a plain portion l2'h`aving designation marks thereon such as 1/16, l/S, etc., to indicate theirelative position of the mechanism actuated bythe rotatable grip as will be apparent from the f later description.` l

A -split's'upporting ring',r 1liy is adapted for, detachable securenient to' the grin i andl Acomprises"two similar 'substantially semicircular members l5 and 1G hinged together at`17 and held in proper adjusted position by suitableA fastening' means 18, such as a bolt and nut or their equivalents. with ille bolt passing through the anges 19 produced on' the ends of the ring members opposite the hinge.

This supporting ring carries ears 2Q for supporting an axle 2l, in the forni 'of a short pin, o n which are fulcrumed the depending lugs 22 ot" the lever 23 having 'one end projecting forwardly'to overlie the corrugated ring 5 and on this end of the lever is journalleda wheel 24 for coaction with the corrugations l1 and adapted to normally .occupy one of the depressions of said corrugations to maintain the grip in an adjusted position through the medium of the supportroo' ing ring, the lever and their component parts.

A spring has its body portion coiled about the axle 21, with opposite ends engaging the suppoiting ring and lever, as the stationary and movable members respectively, to normally force said lever in that direction which will cause the wheel to engage the corrugations.

In order to provide for holding the wheel 24 out of contact with the corrugated ring, which is desirable whentraveling through congested trafiic localities, a latch 26 is slidably mounted on the lever 23 adjacent the rear or operating end and ispreferably situated in a slot with the nose of the latch beneath the lever and a push button connected with the latch above the lever so as to be ttl readily operated. This latch is adapted to be moved into cooperative relation with a keeper 27, such as a fixed staple, when the rear or operating end of the lever is depressed and in consequence of which the wheel Q4 is raised and disengaged from the corrugated ring.v To prevent accidental movement ot the latch 26 a small flat spring 28 is fastened to the lever with the free end in engagement with the latch providing sufcient tension to hold the latch in its adjustment.

In practice when running along the less frequented roads the desired position of the grip may be ascertained and then maintained bv means of the attachment so that the speed of travel will be uniform and this is particularly desirable when a number ot people are traveling together on diierent machines for if the speed of all is the same they will be constantly side by side.

Of course do not wish to be limited to the exact details of construction as herein shown as these may be varied within the limits of the appended claims Without departing from the spirit of my invention.

Having thus fully described my inven; tion, what I claim as new and useful is 1. A handle attachment for motorcycles comprising, in combination, a corrugated ring for attachment to a handle bar adjacent the rotatable grip, a supporting ring for attachment to said grip, agspring actuated lever carried by the supportingI ring and having one end overlying the corrugated ring, and a wheel journalled on said overlying endfor coaction with the corrugated ring to hold tlie gripin any adjusted position,

2. A handle attachment for motor cycles comprising. in combination, a corrugated ring for attachment to a handle bar adjacent the rotatable grip, a supporting ring for attachment, to said grip, a spring actuated lever carried by the supporting ring and having one end overlying the corrugated ring, a wheel journalled on said overlying end for coaction with the corrugated ring to hold the grip in any adjuste( position, and means to hold the lever in such position that the wheelis out of contact with the corrugated ring.

3. The combination with a motor cycle handle including a handle bar and a rotatable rip mounted thereon, of a split ring comprising two similar members hinged together and adapted to be detachably mounted on the handle bar, means engaging said members to hold the ring in its adjusted position, corrugations formed on only a poi'- tion of said ring leaving a plain portion for indication marks associated with the corrugations, a split supporting ring comprising two similar members hinged together and ada ted to be detachably mounted on the rotata le grip, means engaging the members to hold said supporting ring in its adjusted position, ears projecting from said ring, an axle mounted in said ears, a lever, lugs thereon to fulcrum the lever on the axle, a Wheel journalled on one end of the lever for coaction with the corrugated ring and means to force the lever in that direction which will normally hold the wheel in contact with said corrugated ring.

`4. The combination with a motor cycle handle including a handle bar and a rotatable grip mounted thereon, of a split ring comprising two similar members hinged together and adapted to be detachably mounted on the handle bar, means engaging said members to hold the ring in its adjusted position, corrugations formed on only a portion of said ring leaving a plain portion' for indication marks associate( with/the corruigations, a split supportinging comprising for coaction with' the corrugated ring, a'

spring coiled on the axle with its ends in engagement with the supporting ringand lever to force the latter in that direct-ion which will normally hold the wheel in contact with the corrugated ring, a latch slidably mounted on the lever, a spring carried by said lever and engaging the latch to prevent accidental movement of the latter and a keeper on the supporting ring to be en gaged by the latch when the lever is positioned to disengage the Wheel from the cor rugated ring.

In testimony whereof, I have hereunto aliXed my signature.
